Stefanos Tsitsipas and Nick Kyrgios hailed Denmark’s Holger Rune as a potential multiple Grand Slam winner — but also have fears about the “tennis-obsessed” teen burning out.
The 19-year-old Rune shocked Novak Djokovic to clinch his first Masters title in Paris in November, cementing his status as one of the most promising young players on tour.
In doing so he became the youngest winner of the Paris tournament since an 18-year-old Boris Becker in 1986.
He is the first Danish man to break into the top 10.

Speaking ahead of next week’s Australian Open, home hope Kyrgios called Rune “one of the best talents that we have in the sport”.
“He’s got the ability to win multiple Grand Slams. If I was Denmark, anyone who had Holger Rune, I would just make sure they support him, give him all the support,” said the Australian.
